Headscratchers / Mario Kart: Double Dash!!

• So where does the Bowser Shell Item come from?
  • Maybe it's a replica.
  • If Bowser and his son are as close to normal koopas as the games like to imply, then their shells are probably removable and they probably have more of them in stock.
  • It's a magic copy. It didn't actually come from any koopa.
